An ammonia absorption device is added based on the existing ammonia stripping principle, thereby achieving the purpose of removing and recycling ammonia nitrogen with high concentration. The ammonia stripping device has simple treatment process, reliable running, no secondary pollution and remarkable effect on treatment of the ammonia nitrogen with high concentration. The ammonia stripping device is further provided with the ammonia absorption device, and the recycled ammonium sulphate can be recycled after being concentrated, thereby not only saving sources, but also bringing certain benefits to manufacturers.
Description
Technical field
The utility model relates to water treatment field, and a kind of ammonia stripping device is provided especially.
Background technology
Contain ammonia nitrogen in many trade effluents, the industry of discharging high-concentration ammonia nitrogenous wastewater has: iron and steel, oil refining, chemical fertilizer, inorganic chemical industry, iron alloy, glass manufacturing, meat processing and drink production etc.A large amount of ammonia nitrogen waste waters enter water body not only to be caused water nutritionization, causes water body black smelly, and will increase difficulty and the cost of giving water treatment, even to crowd and biological generation toxic action.The main method of removing ammonia nitrogen has: physics method, chemical method, biological process.The physics method contains treatment technologies such as reverse osmosis, distillation, soil irrigation; Chemical method contains treatment technologies such as ion-exchange, ammonia stripping, break point chlorination, burning, chemical precipitation, catalytic pyrolysis, electrodialysis, electrochemistry; Biological process contains treatment technologies such as algal culture, biological nitration, immobilized biotechnology.There are physics method and chemical method a variety of though handle method for treating ammonia-nitrogen wastewater, also do not have a kind ofly can to take into account that flow process is simple at present, reduced investment, technology maturation, control makes things convenient for and the technology of all respects such as non-secondary pollution.
Existing technology is comparatively complicated to the method for treating ammonia-nitrogen wastewater technical process, and cost is higher, and more topmost is that secondary pollution is comparatively serious.Present technique is primarily aimed at that the some shortcomings part of existing ammonia nitrogen waste water treatment method puts forward: such as to the high-concentration ammonia nitrogenous wastewater difficult treatment, cost of investment is too high, energy consumption is big, complicated operation and be not easy to control etc.
The utility model content
The purpose of this utility model provides a kind of ammonia stripping device, handles technical process complexity in the ammonia nitrogen waste water in the prior art to solve, cost height, problem such as secondary pollution is serious.
A kind of ammonia stripping device that the utility model provides, it is characterized in that: described device is made of stripping tower 1 and absorption tower 2;
---wherein, described stripping tower 1 comprises a tank body, and the inside of tank body is provided with spittle separator a 101, liquid distributor a 102, hold-down grid a 103, filler a 104, filler back up pad a 105, liquid re-distributor 106, hold-down grid b 107, filler b 108, filler back up pad b 109 from top to bottom successively; The top of tank body is provided with ammonia outlet 110, is provided with water-in 111 in the junction of tank body and liquid distributor a 102, is positioned at filler back up pad b 109 following tank walls and is provided with blast inlet 112, and the low side sidewall of tank body is provided with water port 113 simultaneously;
---described absorption tower 2 comprises a tank body, and the inside of tank body is provided with spittle separator b 201, liquid distributor b 202, hold-down grid c 203, filler c 204, filler back up pad c 205 from top to bottom successively; The top of tank body is provided with exhaust port 206, junction at tank body and liquid distributor b 202 is provided with sulfuric acid import 207, be positioned at filler back up pad c 205 following tank walls and be provided with ammonia import 208, the low side sidewall of tank body is provided with ammonium sulfate discharge outlet 209 simultaneously;
---use pipeline that the ammonia outlet on the stripping tower 1 110 is connected with ammonia import 208 on the absorption tower 2.
Wherein, the ultimate principle of stripping tower: air being fed in the waste water, make that dissolved gas and easy volatile solute change gas phase over to by liquid phase in the waste water, is its impellent that is changed over to gas phase by liquid phase by the concentration difference of stripping material in liquid and gas.Free ammonia is easy to overflow from water, and the pH value of water is reached about 11, and water temperature reach 45 the degree more than then can impel ammonia from water, to overflow, Fig. 1 is the profile and the internal structure of Ammonia blowing-out tower.
Filler is set in the stripping tower, and customary filler has Pall ring, Raschig ring and structured packing etc.The effect of filler mainly is to promote fully contacting of air and water.Sewage is showered into from the top of tower on the filler through liquid distributor and forms water droplet or vaporific, from top to bottom drip in filler space, simultaneously with blower fan or air compressor from tower bottom blowing send air, water, gas can fully be contacted, water droplet constantly forms, fragmentation, and free ammonia is gaseous state and overflows from water.
The ultimate principle on absorption tower: its internal structure is similar to stripping tower, the ammonia amount that goes out through the stripping tower stripping is bigger, can be produced the bigger wasting of resources as not recycling, and ammonia is a foul gas, environmental pollution is comparatively serious, so adopt ammonia absorber that ammonia is absorbed, the ammonium sulfate that obtains is sent the workshop back to and is reclaimed.
The ammonia stripping device that the utility model provides, its advantage is: the ammonia nitrogen waste water obvious processing effect of the treatment process simple operation of this device reliable and non-secondary pollution, especially high density; And this device attaches the ammonia absorption unit, and the sulfate of ammoniac of recovery concentrates the also recyclable utilization in back, has so not only saved resource, can also bring certain profit for producer.
Description of drawings
Below in conjunction with drawings and the embodiments the utility model is described in further detail:
Fig. 1 is the internal structure synoptic diagram of stripping tower;
Fig. 2 is the internal structure synoptic diagram on absorption tower.
